Yes, it would be! You can just edit sage/calculus/equations.py (inside devel/sage of wherever you have it installed) and send us the patch. At least that process has lots of documentation: http:// www.sagemath.org/doc/developer/producing_patches.html - Robert --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
